Abstract
The invention relates to a feed water treatment process for the printing and dyeing industry. The process comprises the following steps: lifting river water in a river water collection tank into a coagulation tank by using a raw water lifting pump, adding a coagulant into the coagulation tank, and performing coagulation reaction on the river water and the coagulant; causing the reacted river water in the coagulation tank to naturally flow into a precipitation tank, performing solid-liquid separation on the river water, causing the separated river water to enter an intermediate water tank, and causing sludge to enter a sludge tank; balancing the water outflow of the precipitation tank by using the intermediate water tank, and simultaneously controlling the inflow of water entering the next unit; pumping the water in the intermediate water tank into a quartz sand filter by using a pressure pump, filtering the effluent of the intermediate water tank by using the quartz sand filter, and collecting the filtered water for a workshop to use by using a production water tank. The process has the advantages that printing and dyeing water can be obtained by performing coagulation reaction on the river water and performing precipitation, filtering and the like; the whole process flow is simple; in addition, a large amount of printing and dyeing water can be provided for the workshop, and the production cost is lowered.
Description
Technical field
The present invention relates to a kind of dyeing handling technology of water supply.
Background technology
Printing and dyeing are referred to as again dyeing and finishing, are a kind of processing modes, are also dyeing, stamp, rear arrangement, the general name of wash water etc.; The dyeing and finishing specialty of undergraduate course has been incorporated to light chemical engineering specialty now; At the Neolithic Age before six, 7,000 years, our ancestors just can dye redness by burlap by enough hematite powders.The primitive tribe that lives in Chaidamu Basin, Qinghai Province promise wood flood area, can dye Huang, red, brown, blue isochrome knitting wool, weaves the felt with colour play.In period in business week, staining technique improves constantly.In the handicraft workshop of imperial palace, be provided with full-time government official and " dye people " and come " palm dyes grass ", management dyeing is produced.The color dyeing also constantly increases.To Han dynasty, staining technique has reached quite high level.
In printing and dyeing are produced; the quality of dyeing water; as turbidity, colourity, hardness, pH value etc.; effect to printing and dyeing finished product has a great impact; as contained a large amount of suspended substance particulates in water, can make finished surface occur spot and color spot; much higher hard easily makes dyestuff and auxiliary agent produce precipitation, causes dyeing inhomogeneous and colour brightness and color fastness decreased.Therefore the quality of the quality of dyeing water is most important, and if directly buy, cost compare is high, is therefore desirable to provide at present a kind of production technique, can make river can use after by art breading.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of river can processing and uses the extremely dyeing handling technology of water supply of printing and dyeing.
In order to solve the problems of the technologies described above, technical scheme of the present invention is: a kind of dyeing handling technology of water supply, and its innovative point is: described step is:
A) water in river water collecting basin is promoted in coagulation basin by former water lift pump, in coagulation basin, add coagulating agent, and stir by mechanical stirrer, make, between river and coagulating agent, coagulating occurs, the mud producing after reaction is discharged and is entered in sludge sump from the mud sewage draining exit of coagulation basin bottom;
B) in coagulation basin, reacted river, from flowing in settling tank, carries out solid-liquid separation to river, and separated rear river enters in intermediate pool, and mud enters in sludge sump;
C), by the aquifer yield of the balanced settling tank of intermediate pool, control the flooding quantity that enters next unit simultaneously;
D) water in intermediate pool is pumped in quartz filter by force (forcing) pump, utilizes quartz filter to filter the water outlet of intermediate pool, and the water after filtration is collected by water of productive use pond, and the water after collection can be for workshop water;
E) operating pressure in quartz filter reaches after certain value, the clear water of drawing back in water of productive use pond by backwash water pump is squeezed into strainer from filter bottom, flush filter filtering layer, thereby reach the object of backwash filter filtering layer, filter backwash water outlet enter river water collecting basin again the system of entering process;
F) mud in sludge sump is after mud cake by delivering to plate-and-frame filter press press filtration, and outward transport is sent.
The invention has the advantages that: by river is carried out after coagulating, precipitate, after filtration etc. processes, obtain the water that can print and dye and use, whole technical process is simple, can provide many dyeing waters for workshop simultaneously, has reduced and has become product cost; Can also utilize the clear water of production to carry out back flushing to quartz filter, the addle after flushing can be delivered in river water collecting basin and process, very convenient simultaneously.
Embodiment
Dyeing handling technology of water supply of the present invention mainly comprises the following steps:
The first step, water in river water collecting basin is promoted in coagulation basin by former water lift pump, in coagulation basin, add coagulating agent, and stir by mechanical stirrer, make, between river and coagulating agent, coagulating occurs, the mud producing after reaction is discharged and is entered in sludge sump from the mud sewage draining exit of coagulation basin bottom.
Second step, in coagulation basin, reacted river, from flowing in settling tank, carries out solid-liquid separation to river, and separated rear river enters in intermediate pool, and mud enters in sludge sump.
The 3rd step by the aquifer yield of the balanced settling tank of intermediate pool, is controlled the flooding quantity that enters next unit simultaneously.
The 4th step, the water in intermediate pool is pumped in quartz filter by force (forcing) pump, utilizes quartz filter to filter the water outlet of intermediate pool, and the water after filtration is collected by water of productive use pond, and the water after collection can be for workshop water.
The 5th step, operating pressure in quartz filter reaches after certain value, the clear water of drawing back in water of productive use pond by backwash water pump is squeezed into strainer from filter bottom, flush filter filtering layer, thereby reach the object of backwash filter filtering layer, filter backwash water outlet enter river water collecting basin again the system of entering process.
The 6th step, the mud in sludge sump is after mud cake by delivering to plate-and-frame filter press press filtration, and outward transport is sent.
More than show and described ultimate principle of the present invention and principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and specification sheets, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
